Error messages

Waqar Razi — Tue, 14 Dec 2010 21:12:32 GMT

We have 8 nodes Oracle RAC cluster. We are getting the following error messages in the /var/log/messages on one of the servers:

Dec 12 02:30:27 apple EV_AGENT[7900]: Agent Main --Estream construct failed
. Err: RWSockErr: in RWSocket::getpeername: BADF
Dec 12 02:31:52 apple EV_AGENT[7900]: Agent Main --Estream construct failed
. Err: RWSockErr: in RWSocket::getpeername: BADF

Can some one please give me any clue about them and what should we do to get rid of them?

Could be issue with the kernel version, refer the Red Hat Bugzilla â Bug 112891

https://bugzilla.redhat.com/show_bug.cgi?id=112891

if this does not fix, provide more details on hardware,PCI cards kernel, and OS installed....

"getpeername" is a system call, and BADF is an error result, suggesting that the program gave the system call a bad file descriptor. You can use the command "man 2 getpeername" to get more information about the system call if you want.

If there are no other anomalous messages, then I don't see how the bug V Murali mentioned could be relevant: obviously the EV_AGENT process is not being killed here. Also, if the oom-killer was running, you would most likely see a *lot* more log messages.

Knowing the versions of your Linux distribution and the Oracle RAC would be very important here.

The messages don't look like standard Oracle error messages.

Googling for "Oracle EV_AGENT" and looking at the results suggests the messages might be produced by the Enterprise Vault component of the Veritas/Symantec Netbackup product.
